Animating the geometry

With our liquid simulation basically working the way that we want, it's time …to keyframe the object so we can pour the liquid from one vessel into the other. …To make that happen, we'll need to make this tumbler a passive collider. …Co ahead and select that tumbler and go into the N mesh menu and choose Create …Passive Collider. And now I'm ready to animate this locator here. …The locator is the parent of the passive collider that's containing the water. …It's also the parent of the renderable bottle. …But before we make any keyframes, we're going to want to disable the evaluation …of nucleus. Because if we try to scrub around in our …timeline while nucleus is enabled we're going to have performance issues.…

We want to go into the Modify menu and choose Evaluate Nodes and turn off nucleuses. …I want to mention that this Evaluate Nodes menu can sometimes be problematic …and you may notice that the visual state of these check boxes does not reflect the …actual state of whether the particular node type is being evaluated or not. …

Bring scenes to life by building realistic fluid simulations in Autodesk Maya. In this advanced course for visual effects designers and animators, author Aaron F. Ross shows you how to simulate foam and bubbles, liquid being poured, and volumetric liquid in a 3D container. Techniques include rendering particles with the Fluid shader, colliding particle fluids with polygons, storing simulations with disk caches, converting particles and fluids to smoothed polygons, and texturing 3D fluids.
